Getting +/- 150V output from an opamp with 5x gain

A time constant of around 1hz would work. Thanks jim you're a hero :) Now onto the next issue.

By DC offset servo I mean an opamp integrator that I use to bias a triode to maintain a DC null at the output of the stage. As in the non inverting input is attached to ground and the inverting input is attached to the output of the stage and I adjust a trimmer so the opamp outputs a proper bias voltage to maintain a DC null at the output of the stage based on its input.

A question well stated is halfway answered.

Bravo - that was very clear !

thanks, and good luck !
